Application filed April 24, 1985. Serial I0. 25,501.

This invention relates to new and useful improvements in fireextinguishers. In many cities and towns large numbers of houses arebuilt with inflammable roofs which are covered with wooden orcomposition singles, prepared roofing and the like. Fires are frequentlycaused by sparks and embers from nearby fires or burning structures.

The object of my invention is to provide unimproved form of fireprotection for inflammable roofs and to carry out the same by equippingthe roof with means for supplying and substantially covering the roofwith a sheet of water.

A further object is to provide means for protecting the sides of thehouse as well as I the roof.

A particular object of the invention is to comblne with the usual ridgeroll or other ornamental finishing member of the roof. a. conduit forconducting and spra ing the water, thus making the extinguis er of apleasing appearance, rather than unsightly.

A construction designed to carry out the invention will be hereinafterdescribed together with other features of the invention.

The invention will be more readily under stood from a reading of thefollowing specification and by reference to the accompanying drawings,in which an example of the invention is shown, and wherein:

Fig. 1 is an isometric view of a housing having its roof equipped withextinguishers constructed in accordance with my invention,

Fig. 2 is an enlarged cross-section taken on the line 2-2 of Fig. 1,

Fig. 3 is a sectional view of an eaves sprinkler, and

. .Fig. 4 is' a sectional view of another form of sprinkler.

In the drawings the numeral 10 designates the tubular member of anordinary ridge roll such as is used on the ridge of a shingle roof.Atthe bottom the roll is bent outward along each side to form divergentflanges 11 by which it may be nailed to the roof. In order to utilizethe tubular member as a water conductor the flanges and the member attheir line of intersection are $01- dered together as is indicated at12. Along each side of the member 10 perforations 13 are provided justabove the flanges and below the center of said member.

Water supplied to the member 10 will be discharged through theperforations, thus ow1ngh down the roof to form a fire ex tin 1s or orpreventive or if desired to coo the 'roof in hot weather. Water may besupplied to one or both ends of the member 10 in any suitable manner,and where supplied to oneend only,-the other may be plugged.

For protecting the sides of the house I employ a conductor 10' (Fig. 3)having a flange 11. and formed from a single sheet of metal rolled likethe ridge roll. A strip of solder 12' seals the tubular member and formsa water tight joint. The flange may be nailed on or under the shinglesat the edge of the roof or it may be fastened under the eaves. Theperforations 13' are in the lower side of the member 10 so as to spraystreams of water downwardly and arrest sparks and the like. 7

In Fig. 4 I have shown another form which is like the form in Fig. 3except the perforations 14. are positioned over the flange. This stylemay be used at the intersection of a roof and a side wall. In Fig. l

a service pipe 15 including a cut-off valve 16 extends up one, corner ofthe building and connects to a Y connection 17 uniting two edgeconductors one of which is connected by a T joint 18 with the ridgeroll. The connections may he made in any suitable manner.

Various changes in the size and shape of the different parts, as well asmodifications and alterations may be made within the sco e of theappended claims. *hat I claim, is:

1. A roof water conductor comprising a sheet having a portion rolled andjoined to form an elongated liquid conduit and having a portionprojecting from said joint to provi e a continuous longitudinalattaching flange, said conduit being provided "with perforations in thelower sector of its rolled portion.

2. A ridge roll comprising a sheet rolled and secured togetherintermediate its ends to form an elongated 'water conducting memberhaving perforations only in the sector adjacent said 'unction line, saidends being projected in iverging directions to enclose the ridge of aroof and provide continuous attaching means.

In testimony whereof I atlix my signature.
